To all t may concern.'

Be it known that I, ARTHUR VVURDAoma l citizen of'the United States,residing at N orniandy,` St. Louis County, Missouri, have invented acertain new and useful Improvement in Chairs, of which the following isa specification, such as will enable others skilled in the art to whichitappertains to make and use the saine. l0

My inventionrelates to furniture and consists in an improved chair orrocker construction. v 0

The object of myinvention. 1s to provide a simple economical chairhaving a yielding back, to provide a chair which may be easily assembledand disassembled for shipping or i storing, and to provide a chair whichmay be used outdoors as well as indoors without. deterioration due tothe weather.

In the accompanying drawings which illustrate my invention- Figure 1- isa side elevation ot my *improved chair, the dot and dashI linesindicating the modification of the chair to produce a rocker. v

.Figure 2 is a rear elevation of thesame.

Figure 3 isa vertical section on line 3-3 of, Figure 2.

Figure 4 is a 4--4 ofFigure 2. Figure 5 is a, rear elevation corresonding to Figure 2 but' showing va. modiie construction.

The chair comprises four straight legs, referably dis osed vertically,the rear legs being indicate at 1 and the front legs at 2. A rear rail 3connects the/rear legs 1, a front rail 4 connects th'efrontlegs 2, andside rails 5 connect 'a front and a rear leg on each side of the chair,respectively. The chair seat is formed by' one or more boards 6extending across opposite rails. All of l'the parts mentioned arerectangular in Sha e to facilitate their preparation and assem ly, thelegs being gained vnear their upper ends to receive rails and formabetter joint. e

Spaced below each rail is "a rung connecting the legs, the rear rung'being indicated at 7, the side rungs at 8 and the front rung A Vat 9.

y My invention consists particularly in the back and its application tothe chair. In

the preferred form, the back consists in a single board 10 thin enoughto be flexible,

t0 a limited extent, when under pressure horizontal section on lineVfrom the back of a person sitting upon the chair. The width of the boardis preferably the' same as the distance between the rear legs 1 and theboard extends down below the seat a substantial distance and is soinclined that itextends between these rear legs and braces themtransversely of the chair. The lower end of the board is securedto rearrung 7 by means of bolts 11 and near the chair seat the back is securedtoy rear rail 3 by means of bolts 12. The projection of rail 3 to therear of rung 7 and the still further rearward projection of seat 6rovides means forinclining the back formingl board as shown.vBy-tiglitenvEKO ing bolts 12, board 10 `is drawn against the rear edgeofvseat 6 and the extended bearing ofthe seat' edge and the back forms apivot about which the` back may bend as indicated in Figure 3 andlessens the likelii hood of splitting of the board under pressure.

piriifi. i

ile I have illustrated the single board 10 as the preferred backconstruction, similar results will'be` obtained, and ossibl costs` willbe lowered, by the use o a bac formed of a plurality of strips, such 'asin- In use, the back described aords a firm dic-ated in Figure 5, inwhich the strips 13"v are shown connected near their lower end by across piece 14 and near their upper end by a cross piece 15. It desireda cross piece 16 may be .provided adjacent to. the'back rail 17 toreceive the bolts 18 and distribute thel bolt pressure to the strips 13.

Obviously, the cross piecesv 14,' 15 and' -16 v may be omitted and abolt provided foreach strip at the rung 19 and at rail 17.

Other modiications of my invention will suggest themselves in themanufacture of my improved chair and I contemplate such variations asare included followingclaims.

I claim:

1. In a chair a seat, front and rear legs supporting said seat, .a rearrail rigidly Qonin the scope of the 4 nected with the rear legs belowsaid seat, a rung connected with Ysaid rear legs in front of the planeof said rail, and an upwardly and rearwardly inclined back member havingits lower portion attached to said rung and its intermediate portionattached to said rail.

2. In a chair a seat, front and rear legs supporting said seat, a rearrail rigidly connected with the rear legs below said seat, a rungconnected with said rear legs in front of the plane of said rail, and aflexible back a level of said seat to form a yielding back for thechair.

4. In a chair, a seat, a back extending from below said seat to abovethe level of said seat and consisting in a single substantially straightexible board secured at close intervals near said seat and at a pointbelow said seat and unsecured above said seat so as to bend about therear edge of the seat as a pivot.

5. In a chair, a seat, spaced rear legs sup` portin said seat, and .asingle exible board secure adJacent to said seat, the lower por- `wardlytherefrom above said tion of which board extends between and braces saidlegs and the upper portion of which board projects above the level ofsaid seat and forms a yieldingback for the chair.

6. In a chair, a seat, rear legs, a rail beneath said seat andconnecting said lees, a rung below said rail and spaced therelrom andconnecting said legs, and a back consisting of a flexible board securedto said rung andto said rail and extending upscat and unsecured abovesaid rail. A

7 In a chair, rear legs, a rung between said legs, a rear rail at thetop of said-legs and'projecting rearwardly thereof, a seat above saidrail projecting rearwardly thereof, and a flexible back-founding boardthe lower portion of which is held rigid by being secured to said rungand rail and the upper portion of which is positioned b the rung andrail and the rear edge of Sai seat so as to incline rearwardly above thelevel of said seat. i

8. In a chair,'rear legs, a rung between said legs and below the topsthereof, a seat projecting rearwardly of said legs, a flexible boardsecured to said rung extendin upwardly therefrom and forming a bac forthe chair,a rear rail at the tops of said legs in front of the rear edgeof said seat, and

means drawing said board against the lower edge of said rail and againstthe rear edge of said seat. l

In testimony whereof I hereunto alix my signature this 12th day ofAugust, 1924.
